Safety Data Sheet
Getting an SDS for 2-Aminophenol
A Safety Data Sheet is written for a product, not for a substance: the supplier of the grade you actually buy issues it, so two suppliers of 2-Aminophenol issue two different sheets. That is why there is no single authoritative SDS for a substance to download — what there is, is the job of collecting the sheets for the products you hold and keeping them current as suppliers revise them.
04 · Precautionary statements
2-Aminophenol precautionary statements
CLP Annex VI assigns 11 precautionary statements to 2-Aminophenol. They are grouped the way a label groups them: what to do before handling, what to do when something has already happened, how to store it and how to dispose of it.
Prevention
What to do before and during handling so the hazard never happens.
Response
What to do once exposure, spillage or fire has already happened.

05 · Names in the regulation
2-Aminophenol name in 23 EU languages
CLP Annex VI Part 3 is published in every language edition of the regulation, and the identification column is written out in each of them. Nothing below is translated by us: each line is the name as that edition prints it. Under Art. 18(2) the substance name from Annex VI is a lawful product identifier, so this is the wording to put on a label going to that market — and where the cell lists several designations, any one of them qualifies.

All 23 language editions of Annex VI carry this entry. Irish is the twenty-fourth official EU language and has no line here for a different reason: no consolidated CLP text has ever been published in Irish, so there is no Irish edition of Annex VI to quote a name from.

What does a 2-Aminophenol label have to show?
Under CLP Annex VI the label for 2-Aminophenol carries the pictograms Health hazard and Exclamation mark and the signal word is Warning.
Is 2-Aminophenol flammable?
CLP Annex VI assigns 2-Aminophenol no flammability hazard class. That is not a statement that it cannot burn: the harmonised list only records the hazards that were assessed for it. The flash point reported for it is 168 °C (334.4 °F) (HSDB).
Is 2-Aminophenol a carcinogen?
CLP Annex VI records no harmonised carcinogenicity classification for 2-Aminophenol. Annex VI is a list of agreed classifications, not a list of substances found safe, so this is an absence of a classification rather than a clean bill of health.
What is the boiling point of 2-Aminophenol?
The boiling point reported for 2-Aminophenol is 243 °C (469.4 °F), at 760 mmHg (DOE PAC).
What is the melting point of 2-Aminophenol?
The melting point reported for 2-Aminophenol is 174 °C (345.2 °F) (DOE PAC).
How should 2-Aminophenol be stored?
Store in tightly closed containers in a cool, well-ventilated area. Aminophenols must be stored to avoid contact with strong oxidizers (such as chlorine, bromine, and fluorine), since violent reactions occur. /Aminophenols/ (Hazardous Substances Data Bank (HSDB))
